Parse Markdown inside html tags if in separate lines

As in:

<span>

**Bold**

</span>

Obsidian doesn’t render markdown inside of HTML, even when they’re on the same line. No Markdown inside HTML - Obsidian Help

You could use all HTML:

<span><strong>bold</strong></span>
<span>
<strong>bold</strong>
</span>

Or use a non-HTML method to put the text in a “container” (callouts or other predefined markdown) to which you give the same characteristics as the intended span—assuming the characteristics are things CSS can do, such as styling, rather than something you need javascript do to.

Or use a plugin that creates such containers (Regex Mark is one) and the same plugin or another one that lets you use scripts.

That’s unfortunate. But thanks for the info.
